So I have two routers in my house, a WRT600N and a WRT54G, both are running DD-WRT. The WRT600N is the primary router, and the WRT54G is configured to be a wireless bridge, so any device connected to it's ethernet ports get an IP via DHCP from the WRT600N. This setup is working fine & I am getting the optimal amount of performance I can expect over a G-band wireless router.

Previously, I had the Sorenson SR-200 router hooked up to the wireless bridge, then the VP200 hooked up to the Sorenson router, so it was doing double NAT. The SP200 router had a static IP address on the WRT600N, and that IP address was in the DMZ. This setup worked great.

However, I got tired of the SR-200 router being in the way all the time, so I figured out how to change the IP address of the VP200 to where it could be hooked up directly to the WRT54G. So, I set this up to where the VP200 was connected directly to the WRT54G, and it had a static IP address from the WRT600N, which was in the DMZ.

As things sit now, it works, but not as well. I'm receiving 30fps w/ full bandwidth, but I'm only sending 15fps w/ full bandwidth. I'm not sure why this is because the VP200 is in the DMZ. I'm sure it's because of some setting that the SP200 router had that I'm not replicating, so I'd like to figure out what that is rather than go back and hook the SP200 router back up. I'm assuming some kind of UPNP setting or H.323 thing? Any help or suggestions appreciated.

Further testing revealed that it's primarily a wireless interference problem. Using iStumbler, my laptop picked up 30 wifi signals on the 2.4GHz band. Even though I was using channel 11, so were 5 others very close to me. To much interference. Switched over to channel 3 which seems to have solved my problems.

However, this also got me thinking that I'd like to get off of the 2.4GHz band once & for all because of the interference problems. I compulsively bought a WRT150N on eBay & was going to replace my WRT54G with it, thinking since it was an N router, it would be 5GHz compatible. Turns out I was wrong, & now I'm the proud owner of a WRT150N that I don't really need.

Looking forward, I need to do more research into the best options for setting up a 5GHz N wireless bridge. I refuse to buy a commercial wireless bridge like the WET610N, when I can get more functionality out of flashing a cheaper router with DD-WRT & using that as a bridge. Unfortunately, that severely limits my options because I want to stay with Linksys & avoid the saucer type models, which pretty much means another WRT600N. However, those are going for $200+ on eBay right now... so, still investigating.

Mainly, I'm just updating this for others to find & comment on. If you have any questions, feel free to ask.

use port forward not dmz

connect vp200 to wrt54g and use dhcp to get address from wrt600n

then uncheck dhcp and set up pf on wrt600n dont have be on 192.168.0.125

Is QOS enabled on your WRT600N?

If QOS enabled then try disabling it and test again.

unforunately- this is where you need to start tweaking your wireless bridge. It worked before because of double nat and the wireless bridge didnt have to understand the settings so it just passed the network packets along. Since you eliminated it, now you are INSIDE of wireless bridge security settings and nat. you need to tweak one setting at a time till you find what works. Unforunately what I know works on one persons vp and router doesn't necesarly work on another person home. TOOOO many variables. F/w rev on both? dsl ? does cable modem hav nat? etc, etc.

each time you tweak a setting, you need to keep track so you can go back and eliminate the unnecessary tweaks.

like techbill and qwerty said try thier suggestions. sometimes routers settings makes NO sense and shouldnt affect things but it does with VP.

-port forward?
-qos on/off?
-Filter Internet NAT Redirection unchecked?
-Filter Multicast ?
-CTS Protection Mode disabled?

good luck!
 
Just curious... why are people suggesting to use port forwarding rather than DMZ? One of the nice things about DD-WRT is that it's UPNP function actually lets you see what ports are being forwarded. So, I turned on UPNP, and verified that it was working by starting a BitTorrent client on my laptop. Sure enough, it showed the port being forwarded correctly and my BitTorrent client showed the port as being open. So, it works. Then, I made a test call with the VP-200 in the same "problem" configuration (hooked up directly to the wireless bridge), and I didn't see any ports being opened via UPNP. This leads me to believe that the VP-200 is getting all of the necessary port connections it needs.

QoS is turned off, though I have considered enabling it just because I have Crashplan running in my home at all times on several computers, and if it's running, the VP-200 is way too slow. I have seen people say it doesn't work, or doesn't work well, but I do plan to try it eventually once I get it working in it's current state optimally.


Anyway, as per my previous post, my current problem seems to primarily be due to wireless interference. Not much I can do about that except keep an eye on it and hope my neighbors stay off the channel I'm on.

I do appreciate all the advice so far.
 
you are right its a wireless issue- but you stated it worked with a extra router on it ON the wireless bridge. Was tryhing to help you to figure out the nat issues.

I do use DD-WRT myself with a WRT600N. If you enable QoS, you can give the VP-200 priority so it does not run "too slow". If you assigned IP address 192.168.1.125 like me, make sure you have /32 to limit it to that particular IP address.

ok,i have figured out setting up 3 routers one is actually a dsl modem with built in firewall software,i hooked up vp 200 with sr-200 router to my dad's dsl modem by verizon in sarasota area florida while on vacation i had to use switching ethernet hub to spilt his wireless router and my sr-200 router to dsl modem and i set up port forwarding in the verzion dsl modem using this info

vp-200-a port 15328-15348 udp sr-200 wan ip address
vp-200-b port 15328-15348 tcp sr-200 wan ip address
vp200 port 1720 tcp sr200 wan ip address

this setup works if you have port forwarding already set up in sr-200 by vp installer what it does it port forwarding points to sr200 router instead of dsl modem or wireless router
note you can use dmz host on dsl router by other company to point to sr-200 router wan ip address ,the verizion dsl modemdmz host doesnt work

Should that be 192.168.1.125/24?

/32 netmask mean the first IP will be take into account (192.168.1.125 here)

if you want to select the whole subnet you will have to set something like 192.168.1.0/24
